Hi

I want to know which profile will be called when a user without home directory is created.

When I created a user without home directory(by setting in /etc/default/useradd), the user is able to login directly into the main "/" folder but with only read permissions.

Thanks

There are 2 kind of profile file. The first one is the /etc/profile file that is common to all users. The second one is the /home/user/.profile file. That one is executed for that particular user. The home directory could be one of your choices. Let's say you decide that all users have the same home directory, let's say /home/users/, then you will have to modified the /etc/passwd file and also modify permissions on files too to suite your need. You will then edit /home/users/.profile file and fill it with your code.

Note: I don't suggest a common home directory for all users.

I don't want to create home directories for any of the users, actually I am creating users to access CVS(Version Control Tool) for which there is no need of home directory. So in this case when I created a User without home directory, still the user is able to login using the user-id provided for CVS (Only Read Permission)

if you don't need the home directories --- just create the accounts with /tmp as the home directory ... that way your users cannot accidentally mess something up in / if there are files/directories that for some reason got the world-writable bit on ... good luck!
